or YellowRound or WrinkledGreen or YellowAxial or TerminalPurple or WhiteTall- T ; Dwarf- tWhen Mendel crossed homozygous tall plants with homozygous short plants, all the peas from these plants produced tall pea plants in the next generationDominant Trait would be represented as capital I and the recessive trait would be lower case i.Inflated- I ; Constricted- iYellow - Y ; Green - yDominant trait would be a capital R and the recessive trait would be the lower case r. The round seeds have higher starch content and so are used to make pea soup. The wrinkled seeds have higher sugar content and so are used as a fresh, frozen, or canned vegetable.Axial - A ; Terminal - aA cross between homozygous purple-flowered and homozygous white-flowered pea plants results inoffspring with purple flowers, which demonstrates dominance.Purple - P ; White - pThe dominance trait would be represented as a capital P and the recessive trait is represented as a lower case p.Yellow - G ; Green - gDominant trait is represented with a capital G and the recessive trait is represented with the lower case g.Dominant trait is represented with a capital A and the recessive trait is represented with the lower case a.An axial position would grow with leaves going up and flower to the side, while the terminal would grow with nothing but flowers at the top.
